ERNEST BARNES AND GEORGE VIVIAN MARMADUKE EDGE, OF BLUFF, NEW ZEALAND.

H001 FOR BALES AND ZEAGKAGES.

Application filed February 26, 1927, Serial No. 171,099, and in New Zealand November 24, 1926.

This invention relates to means for binding bales, packages or the like, and has for its object to provioe a device that can be quickly and easily operated, is economical in material and has no projections such as rivets which may possibly tear the material bound. Furthermore the improved fastening means according to this invention eliminates the necessity for perforations in the tie or band and enables the tie or band to have asubstantially flat surface.

Broadly speaking the principle underlying the invention comprises forming the ends of the tie or band in such a manner that when'they are suitably placed within retaining means such as a sleeve or collar, on the pressure on the bale package or the like being removed the consequential expansion thereof causes the ends to jamb as by reason of their enlargement they cannot be pulled through said retaining means.

The invention consists in this feature and in the features and arrangements and combinations of parts hereinafter described and more particularly pointed out in the claims.

Referring to the accompanying drawings which illustrate a constructional embodiment of the invention Figure 1 is a perspective elevation showing two pressed bales of wool secured with the improved device,

Figure 2 is a perspective elevation of part of a tie of flat section showing the method of inserting the enlarged ends thereof in the retaining means, Figure 3 is a similar perspective elevation to that shown in Figure 2 but showing the locked position of the ends when the tie has been tensioned owing to pressure on the bale having been released,

Figure 4 is a perspective elevation similar to Figure 2 but showing the tie made of wire substantially circular in cross section while *igure 5 is a corresponding similar view of such wire tie to Figure 3.

ln the embodiment of the invention shown in the drawings, and with particular reference to Figures 1 to 3 the tie or band 2,

made of metal similar to that at present used is gradually thickened at its ends 3 and a one end being preferably more thickened than the other, as is clearly shown in Figures 2 and 3. These ends 3 and a may be thickened by any means Well known in the art such for instance as by dumping up or otherwise. Suitable retaining means such as a sleeve or collar 5 are provided said sleeve having an orifice of such size as to enable both of the ends 3 and 4t to be passed therethrough when in a position such as shown in Figure 2 but which is not sufficiently large to permit said ends being pulled through when tension is applied and the said ends 3, and 42 are in the wedged position as shown in Figure 3. In such a position it will be obvious that the greater the tension the more firmly does the collar 5 hold the thickened ends 3 and 4 in wedged position.

In operation the tie 2 is passed round the bale or the like 1 and the thicker end 3 of tie 2 is pulled through sleeve 5 so that a non-thickened portion thereof lies within said sleeve 5. The other thickened end 4: is then projected through from the opposite side of said sleeve 5, the two ends 3 and l being then substantially in the position shown in Figure 2. The sleeve 5 may then according to circumstances either be let fall by the force of gravity or be pulled towards the thicker end 3 as far as possible, and on the pressure being released from the bale, package or the like, the ends 3 and 4 will be securely wedged as shown in Figure 3.

To open the bales or packages of a simi:

lar nature where considerable pressurehas been applied it is necessary to sever the said tie or band 2 with an appropriate instrument.

In Figures 4: and 5 the invention is shown as applied to a wire tie. It will be evident therefrom that the principle and mode of operation is identically the same. The two ends 6 and 7 of the wire are enlarged by any known and suitable means the end 6 being preferably larger than the end 7. The sleeve 8 has its dimensions such as to enable both ends of the wire to be passed through as shown in Figure lbut on tension being applied will hold the ends of the wire securely wedged when in the position shown in Figure 4.

Claims:

1. A bale strap of the character described, comprising a band having its opposite ends provided with enlarged integral solid tapered portions, and a straight sleeve embracing the overlapped ends of the stra 2. A bale strap of the character describec, comprising a band having its opposite ends provided with enlarged integral solid tapered portions, one end being larger than the other, and a straight sleeve embracing the overlapped ends of the strap.

3. A bale strap of the character described,

comprising a band having its opposite ends ends together when both are embraced by provided with straight sided enlargements the sleeve.
